Spero Therapeutics (Nasdaq: SPRO) is a multi-asset pre-commercial stage biopharmaceutical company in Cambridge, Mass. We are highly committed to advancing novel treatment approaches for bacterial infections with a world-class team of biotechnological and biopharmaceutical experts. The company has a pipeline of novel and highly differentiated antibacterial and rare disease product candidates focused on patients' unmet needs with multi-drug resistant (MDR) bacterial infections. Spero’s lead product candidate, tebipenem HBr, is an oral carbapenem being developed as the first oral carbapenem antibiotic for use in complicated urinary tract infections (cUTI) and acute pyelonephritis (AP). In September 2020, Spero announced positive top-line results from its Phase 3 ADAPT-PO clinical trial of tebipenem HBr in cUTI and AP. Spero is also developing SPR720, its oral antimicrobial agent in development for the treatment of nontuberculous mycobacterial (NTM) pulmonary disease, a rare orphan disease. Spero’s third product candidate, SPR206, is an IV-administered agent being developed as an innovative option to treat MDR Gram-negative bacterial infections.

We believe that our novel product candidates will have a meaningful impact on patient health and significant commercial applications for treating MDR infections in hospitals and community settings.
